How to Upgrade my rezzer with a new kart.
You just bought a new kart for your rezzer system and want to put it into your kartrezzer.
1) Put the box on the ground
2) If the box has a floating text stating "click the update box button in your rezzer manager menu" skip to step 5
3) Look inside the box, (right click, choose edit and choose the content tab), if the content holds an object called "(kart name)upgrade box" copy the content of the box to your inventory
4) rezz the box in front of the kart rezzer
5) Go to the managers part of your rezzer menu and choose the "upgrade Box" button.
6) Wait for the upgrade to complete and your rezzer to restart.
NOTE: i have seen an issue with placing the box to close to the rezzer, as half in the floor,
the rezzer checks if a scripted object is placed within 50 cm of the center of the rezz plate, to prevent rezzing of multiple karts on top of each other,
It can see the box as a scripted object and whispers (kart detected please wait)
Move the box a little futher away from the rezzer floor plate.
